AbstractThis article outlines a collaborative project in development involving participants in the GEM 2 HALIP Activity and the Laboratory for Cryospheric Research, University of Ottawa. Glaciological research in the vicinity of White Glacier, Expedition Fiord, has recently involved the combined use of Structure from Motion photogrammetry methods and ultra-high resolution GigaPan© images to study landscape evolution. Here we propose to apply these techniques to generate a detailed geological map of the area centred on the Between Lake massive sulphide showing. The requirements include (a) sufficient camera resolution, (b) the availability of high-resolution satellite imagery, and (c) ground-based measurements using differential GPS systems. A 4-step approach is proposed that involves limited helicopter survey work to establish ground-control markers; the acquisition of high-resolution, spectrally-rich satellite images such as SPOT6 or WorldView3; the use of panoramic photography using GigaPan©; and targeted sampling of ridges and nunataks to ground truth a preliminary remote predictive geological map. The requirements as well as the mutual benefits to be gained in glaciological and geological research are discussed. For example, improved bedrock mapping could help to better delineate the extent of the massive sulphide deposit, and improve understanding of controls on the subglacial hydrology and basal motion of White Glacier.
